Application filed September 13, 1915. Serial No. 50,445,

To all whom it may concern:

Be it known that we, HENRY H. FISHER and WILLIAM G. BARNES; citizens ofthe United States residing at Evansville, in the county of Vanderburgand State of lndlana, have invented certain new and useful Improvementsin Trolley-Replacers; and we do declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

This invention relates to trolley replacers, particularly to that typewhich employs the feed wire for actuating the device, and has for itsobject to provide a simple and inexpensive replacer of this type toeffectively carry out the purpose for which it is designed.

Another object is to provide a replacer which is practically automaticinits opera tion.

A still further object is to provide a replacer in the form of a movablecarriage slidable on the outer end of the trolley pole.

With these and minor objects in view, our device consists of certainnovel features of construction, combination and arrangement of partswhich will hereinafter be more particularly described and planned andshown in the drawings wherein:

Figure 1 represents a side elevation of our improved trolley replacershowing the movable carriage in retracted position; Fig. 2 is a similarview showing the carriage in extended position; Fig. 3 is a top planview of this improved device; 4 is a bottom plan view thereof; Fig. 5 isa central vertical longitudinal section through the replacer in positionon the outer end of the trolley pole; Fig. 6 is an end View; and Figs. 7and 8 are transverse sections taken respectively on the line 7-7 and 8-$of Fig. 1. i

In the accompanying drawings 1n which similar reference charactersdesignate cor responding parts throughout the several views, 1 indicatesa trolley pole having its outer end substantially squared as shown at 2,said pole being also provided on its outer end with the usual trolley 3which is adapted to underlie the feed wire F. On this squared end of thetrolley pole is a housing 4: in the form of a carriage slidable towardand away from said trolley 8. This housing 4 comprises side plates 5whose outer ends are provided with alined ears 6 havlng bearings formedtherethrough, while integrally joined with these side plates is a topplate 7 A flat bottom plate 8 is joined to the lower edges of the sideplates 5 and 18 provided at its lower end with a suitable hook or otherfastening device 9 for securing one end of a contracting spring 10 tosaid housing or carriage. This contracting spring 10 is secured by itsopposite end to the outer end of the trolley pole adjacent said trolley.From this description, it is evidentthat this carriage t will vmovetoward the trolley 3 unless it is held against the tension of the spring10. In order to hold this carriage in retracted position against thetension of the said spring, we have provided a catch 11 in the form of ahook-like member which coacts with a similar catch 12 on the lower endof the top carriage plate 7. This catch 11 is pivoted at its lower endas at 13 and is provided with a leaf spring 14 for holding it inoperative position. A pair of alined bearing ears 15 formed in the upperside of this housing 4: about midway its ends are provided with alinedbearings therethrough. A. suitable trip member 16 in the form of a leverfulcrumed intermediate its ends between said ears 15, is arsed foractuating the-catch 11. The lower end of this trip member l6is beveledas shown at 17 to en gage the beveled portion 18 of the aforesaid catchmember 11. The outer end of this trip 16 is provided with a pair of cars19 between which a feed wire engaging roller 20 is adapted to revolve,while beneath the under side of said trip is positioned a V-shaped leafspring 21 adapted to normally force the upper end of said trip away fromthe carriage member. For coaction with the ears 6 formed on the outerend of said plates of the housing, we provide the bearing plates 22which have their lower ends secured to the said plates of said housingand their upper ends bent laterally and then extended forwardly toprovide bearing ears 23 whose bearings aline with the bearings of theaforesaid ears 6. Between each pair of bearing ears 6 and 23 is mountedto revolve therein a suitable feed wire guiding roller 24. These rollers2r have downwardly and inwardly inclining edges for guiding said feedwire F into con tact with the trolley 3. The aforementioned feed wireengaging roller 20 is preferably of a length equal to the width betweenthe outer,

sides of the guiding rollers 24. A cable 25 has one end secured to thehook 9 and extends through a suitable guide 26 formed on the trolleypole l and is adapted for returning the carriage a to its retractedposition when the feed wire has been replaced on the trolley 3.

In normal operation, the parts of our improved replacer are positionedas illustrated in Fig. 1 of the accompanying drawings, the trolley polebeing extended-upwardly at-an angle and having its trolley engaging thefeed wire F. However, when said feed wire F is disengaged from thetrolley 3, the outer end of the trolley pole 1 will tend to fly upwardlyunder the tension of the usual spring, not shown, provided t thejunction of the trolley pole with the top of the car for callsing suchupward movement; This operation will cause the feedwire engaging roller20 to strike the feed wire, thereby releasing the catch member 11 andcausing the carriage to move toward the trolley under the tension of thespring 10. The feed wire Fwill then force the upper end of thetripmember downwardly and be guided by the rollers 24: on the trolley 3.After this operation has taken place, electric current will again travelfrom the feedwire to the trolley pole and the carriage can then bereturned to its retracted position by pulling on the cable 25, and thereplacer will then be in position to again restore the trolley to thewire, should it leave the same. 1

Fromthe foregoing description, the construction of our improved trolleyreplacer, the manner of applying the same to use, and the advantagesthereof, will be readily understood and it will be seen that we haveprovided a simple and inexpensive, and efficient'means for carrying outthe objects of our invention; 7

VAlthough we have particularly described the elements best adapted toperform the functions set forth, it is obvious that various changes inform, proportion and in the minor details of construction may beresorted'to within the scope of the appended claims without departingfrom the spirit'or sacrificingany of the principles of the invention;
